By restoring ring tension and sealing, this kit helps recover top-end power and reliability without the cost of OEM-only parts, making it a practical choice for trail machines and workhorse farms alike.\u003c\/p\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX450 Foreman (S\/ES\/FE\/FM)\u003c\/td\u003e\n\u003ctd\u003e1998–2004, 0.25 OS piston ring kit for TRX450 Foreman engines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX450 Foreman FM\u003c\/td\u003e\n\u003ctd\u003e1998–2004, 0.25 OS piston ring set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX450 Foreman FE\u003c\/td\u003e\n\u003ctd\u003e1998–2004, 0.25 OS piston ring set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX450 Foreman ES\u003c\/td\u003e\n\u003ctd\u003e1998–2004, 0.25 OS piston ring set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX450 Foreman S\u003c\/td\u003e\n\u003ctd\u003e1998–2004, 0.25 OS piston ring set\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Reference Part Numbers\u003c\/td\u003e\n\u003ctd\u003e13011-HN0-A01;

Built as a cost-conscious, durable alternative to OEM pricing, it delivers solid fitment and enduring sealing performance, making it a trusted choice for back‑country rides and field work alike.\u003c\/p\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX500 Foreman FA, FE, FM\u003c\/td\u003e\n\u003ctd\u003e2005–2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX500 Foreman FPE, FPM\u003c\/td\u003e\n\u003ctd\u003e2005–2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eTRX500 Foreman (Foreman Rubicon 500 lineage)\u003c\/td\u003e\n\u003ctd\u003e2005–2013 (FPE\/FPM); 2015–2019 (FA\/FE\/FM families and related trims)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eFitment notes based on model family and bore specifications align with a 92.00 mm bore and OS 0.50 oversize used on these Foreman variants.

This OS 1.00 end-gap kit restores compression and minimizes oil loss, delivering solid, reliable power for trail rides, ranch work, and demanding job-site use. It’s a cost-conscious aftermarket replacement that mirrors factory specifications to keep the engine performing like new. The kit targets common wear points in the 300 OS lineup—ring lands, blow-by, and oil control issues—so you can trust consistent sealing and predictable compression across your next ride or shift. With a three-ring design (two compression rings plus one oil ring) and a precise OS 1.00 end-gap, this kit is engineered to maintain seal geometry under the vibration and high-load conditions typical of rugged terrain. The rings use a standard piston ring alloy suitable for the harsh environment of 2- and 4-stroke highway, trail, and farm work, delivering durable performance and repeatable results. Built to Kawasaki specifications, this aftermarket set offers a reliable alternative when OEM pricing isn’t desirable, without sacrificing fit or function.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKLF Bayou 300 (KLF300)\u003c\/td\u003e\n\u003ctd\u003e1986–2004\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKEF Lakota 300 (KEF300) \/ Lakota Sport\u003c\/td\u003e\n\u003ctd\u003e1995–2003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF Prairie 300 (KVF300)\u003c\/td\u003e\n\u003ctd\u003e1999–2002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eBayou 300 variants (KLF300 family)\u003c\/td\u003e\n\u003ctd\u003e1989–2004 (and related variants into early 2000s)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eLakota Sport \/ Lakota lineage\u003c\/td\u003e\n\u003ctd\u003e1995–2003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF Prairie 300 variants\u003c\/td\u003e\n\u003ctd\u003e1999–2002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Reference Part Numbers\u003c\/td\u003e\n\u003ctd\u003e13024-1080\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePiston Ring Kit (OS 1.00 end-gap)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAftermarket Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eKawasaki 300 OS engines: KEF\/KLF\/KVF 300, 1985–2004\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eStandard piston ring alloy (high-grade steel\/cast-iron blend typical for OS ring sets)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnd Gap\u003c\/td\u003e\n\u003ctd\u003eOS 1.00 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRing Configuration\u003c\/td\u003e\n\u003ctd\u003e2 x compression rings + 1 x oil ring (3-ring set)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBore Compatibility\u003c\/td\u003e\n\u003ctd\u003eApprox. 77.0 mm bore (OS 1.00 over standard 76.0 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eOEM \u0026amp; Aftermarket Cross-Reference Information\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003cth\u003eBrand \/ Type\u003c\/th\u003e\n\u003cth\u003eCross-Reference Notes\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e13024-1080\u003c\/td\u003e\n\u003ctd\u003eKawasaki OEM\u003c\/td\u003e\n\u003ctd\u003eOriginal piston ring set with OS end-gap; direct-fit for KEF\/KLF\/KVF 300 engines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e13024-1080\u003c\/td\u003e\n\u003ctd\u003eAftermarket Replacement\u003c\/td\u003e\n\u003ctd\u003eDirect-fit OS 1.00 end-gap kit matching OEM specification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\nIn the box you’ll find the essential rings matched to the KEF\/KLF\/KVF 300 OS bore:\n\u003cul\u003e\n\u003cli\u003e\u003cb\u003eTop compression ring\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eSecond compression ring\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eOil control ring\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eNote: This kit includes the rings only.

This kit provides consistent, long-life sealing and oil control in demanding KVF360 applications.\u003c\/p\u003e\n\u003ch3\u003eComprehensive Vehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModels \/ Series\u003c\/th\u003e\n\u003cth\u003eYears \/ Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360A Prairie 360 4x4\u003c\/td\u003e\n\u003ctd\u003e2003-2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360B Prairie 360 2x4\u003c\/td\u003e\n\u003ctd\u003e2003-2009\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360C Prairie 360 4x4 Realtree APG HD\u003c\/td\u003e\n\u003ctd\u003e2010-2013\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360C Prairie 360 4x4 Hardwoods Green HD\u003c\/td\u003e\n\u003ctd\u003e2004-2009\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360C Prairie 360 4x4 Advantage Classic\u003c\/td\u003e\n\u003ctd\u003e2003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKawasaki\u003c\/td\u003e\n\u003ctd\u003eKVF360C USA variants\u003c\/td\u003e\n\u003ctd\u003e2011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOEM Reference Part Numbers\u003c\/td\u003e\n\u003ctd\u003e13025-0002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003ePiston Ring Set, L, O\/S 0.75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAftermarket Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eKVF360 (Kawasaki Prairie 360), 2003-2012\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOversize\u003c\/td\u003e\n\u003ctd\u003e0.75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRings Included\u003c\/td\u003e\n\u003ctd\u003eTypically 3 rings (2 compression rings + 1 oil control ring)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBore Size (Oversize)\u003c\/td\u003e\n\u003ctd\u003e80.75 mm (standard bore 80.00 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnd Gap \/ Fitment Notes\u003c\/td\u003e\n\u003ctd\u003eEnd gaps designed for standard KVF360 oversize application;
